Description Charalampos Stratakis 2025-07-08 03:12:43 UTC 
Hello,

We are planning to update Cython from 3.0.12 to 3.1.2 in Rawhide.

However python-jnius fails to build with the latest Cython version.

You can inspect the build failures at https://copr.fedorainfracloud.org/coprs/cstratak/Cython-3.1.2/package/python-jnius/

Let us know here if you have any questions.

We'd appreciate help from the people who know this package best, but if you don't want
to work on this now, let us know so we can try to work around it on our side.
Comment 1 Charalampos Stratakis 2025-07-12 01:06:39 UTC 
jnius/jnius_utils.pxi:323:37: undeclared name not builtin: long

Upstream Cython change relevant to the failures: https://github.com/cython/cython/pull/5830

Basically "long" should be replaced by "int".
